Re: Intercooling with water vapour


 emoticon Hi MosaicT30, Dads done lots and lots of drag racing using turbos with no intercoolers, just Water/Methanol injection, he reckons it's the ducks guts. Now Edelbrock make a briliant vari-jection water injection kit emoticon , around a $[sign in to see URL] works well foolproof, and is your solution! Well with some methanol added for more kick. emoticon

Easily plumbed, easy to set up, and will allow you to screw in some ridiculous ignition timing/maps to really get off the mark in a hurry! emoticon

Next, while most will go the front mount route, it does have lots of drawbacks, the biggest one being turbo lag and poor throttle response. Dad reckons to persevere with the top mount, but punch some vents in the bonnet to get rid of the hot air that is causing all the problems in the first place. Now you could get all agricultural and just use an axe emoticon , LOL, but there are so many vents in cars these days, just take a look in some wrecking/recyclers yards until you find something you like the style of, then get a decent panel shop to fit them for you. Fans added under them will help to. Still consider some ultra fine waterjets over the intercooler, and definitely wrap all the exhaust system within the engine bay in quality thermal tape. Do all this and watch your GT EXY sprout wings and fly off the lights, you'll probably need stickier tyres!!

Dad hopes all this helps. emoticon

Well I'm off to get Muddy again, got bogged to the diffs yesterday and needed a tow out, got super Muddy, But them Mum made me go have a bath emoticon , so Dad and me are going out again in the morning to have another splash, tread lightly stay upright, Augustus the X Trail emoticon emoticon

Re:


I too would appreciate the muddy photos., but Augustus.. maybe next time you can get your "dad" or "mum" to type up the post instead.. that way we aren't trying to translate chilidish story-telling on a well-regarded internet forum... just a thought.

In regards to the OP regarding water injection, go for it, mate! There's certainly a few doubters on this forum, but also some people interested in seeing boundaries challenged (and they love their exy's just as much as you!), so if you're up for the effort involved, then heed the advice people have been giving and instead of feeling discouraged, USE it to your advantage. Good luck with, champ!

Re: Intercooling with water vapour


HI Guys, well, the first person who doesn't really like my writing style! Oh well, no one else has complained as yet so well keep to it. Just some fun and something a bit different, I hope you read my posts to your Exy.

I write stories of our adventures as well, they will wind up somewhere on the forum soon, just need to figure out where to put them without offending anyone. Any suggestions?

We will post some photos of getting bogged shortly, and me bathed in mud, also one of me going into tripod mode. Once Dad works out how to do it! Post photos that is, he's an expert at getting me on 3 wheels and 2, would love to do 2 on the same side, but that would freak Mum out completely... LOL!

One other thought here about intercooling, Dad had some mates who were running turbos before the easy availability of intercoolers using "Poor Mans" intercooling, NOS, (Nitrous Oxide) Hang on!!! emoticon

It works very well, but aint' exactly street legal! But heaps of fun! emoticon

Well, we're off to get Muddy tomorrow, we'll be sure to get some pics, aint like there's a shortage of cameras in our household, I carry around at least 5 high end Canons at all times, with all their lenses and accessories!

Stay upright, tread lightly and get your Exy Muddy, we love it, Augustus the X Trail. emoticon emoticon

The child may be the father to the man but in a technical area, the man has better credibility than the child.

In a narrative area such as 'trips' and adventures, the child may give a more interesting perspective.

Re: Intercooling with water vapour


Hi guys, I just turned 3, aren't X Trail years like Dog years, so I'm 21 and no child LOL, seen a lot more of this country than the average 3 year old. I've been to Lake Eyre, and beyond on my first big trip, I was only a few weeks old then, and I've been to the cape and back, no dramas!

Hey this is all meant to be fun isn't it?

Have a great day Augustus the X Trail, who love s getting Muddy! emoticon

BTW Mums name is Elizabeth & Dads name is Darren. emoticon

Yes, it is supposed to be fun as well as informative and X Trail years can be like dog years.

It's only a perception and translation difficulty caused by the unusual third person perspective which may sometimes cause the point of your discussion to be harder to follow.

No big deal. Everyone has his/her own way of doing things.

At 18 months, my baby has barely crossed the street but yours has undertaken major voyages of explorationemoticon

Re the intercooler, I seem to recall that a member mentioned in the trips section that his was knocked out of place during a trip which showed a decent water crossing.

My thought at the time was that the damage may have been caused by the impact of the water directly onto the the radiators/intercooler etc through the wide open design of the bumper.

I note that you suggest fitting a fine mesh grille over the slot to slow airflow in order to enhance heat interchange.

Maybe that extra mesh would also stop water pressure damage when entering a water source at speed?

I've found that external mesh does stop insects before they hit/block the bendy bits of the inetrcooler, radiator etc.

It should also stop a hammer blow of pond/stream water when water crossing and the new (to me) concept of improving heat exchange by slowing air flow is a real bonus.

Re:


Putting anything infront of the intercooler to try to slow the airflow to get better heat exchange will not work, think about it. All it will do is reduce the amount of air flowing onto the front of the intercooler, less air flow means less heat exchange. Why do you think all us high performance guys put the largest surface area intercoolers that will fit in right at the front of the car with no restriction to air flow and some guys cut part of the bumper/spoiler away to get more of the surface area to the air flow. I have had a fair bit to do with modern turbo cars so i do know what i am talking about, also i have read that with turbo diesels it is possible to get the intake charge too cold and this causes incomplete combustion and less power, a little cooler than stock is ok but too much is not good, where with petrol turbo the colder the better.

Re:


HI Augustus the X Trail here, I'm Handing over to Dad for this one.

Hi guys, if air flows too fast over a radiator or Intercooler it has no time to exchange heat effectively, especially fine finned types, don't wish to get too scientific but it is a proven fact. Also if the intercooler or radiator is not properly surrounded, as I see in many big dollar sports setups the air just takes the path of least resistance and just flows around the intercooler or radiator, doing very little. Think about this also, you have a very hot radiator behind your Intercooler, doesn't make sense to me, much better to halve the frontal size of both units placing the intercooler on the bottom where it gets cooler air and reap the benefits. How will a smaller radiator cool it? Where talking about halving frontal area only, thicker cores, and multi pass coolant flows are the answer, contact Aussie Desert Coolers for a workable solution, the worlds leading radiator experts and Austrailan to boot.

Hope that answers some questions, and btw ask any High performance Big Block owner how they cool their engine, especially in small cars, they lay the radiator back or forward, though back works better, as the air tends to escape under the car, and they use Aussie Desert Coolers if they are smart! I have had many Big Block Ford monster engines cracking out huge HP, they have been N/A, Supercharged, turboed and Nitros breathing and this was the only way to keep them streetable and driveable in traffic, including bumper to bumper. I've also played with ultra hot rotaries and lots of ultra quick fours and sixes, of all brands and always reliable, yet big bang for your buck, mega bucks don't always equate to big reliable output. Careful attention to assembly and the correct preparation of the right components, always beats mega bucks if done right.

Back to our little boy Augustus.

And Dogtrail mesh would sure help reduce the "hammer effect" of a fast water crossing, But the X Trail shops grills would do it too and look heaps grouse, cant wait for mine. fitting soon!

Off to get Muddy, and do I ever have a big surprise in store next month, Keep tuned, cause I'm getting a major major upgrade, Yippee!!! Augustus the X Trail emoticon
